Warnings on node startup (version 1.10.2)

The following question appeared online:

I've updated ThingsDB to version 1.10.2 and now see some warnings when the node starts:

compare (!=) direct after function call: ...

What is causing these warnings?

ThingsDB optimizes procedure storage to keep code as compact as possible.

In earlier versions, a statement like f()!='x' was parsed without issue. However, in newer versions, placing ! directly after a function call can be confusing, as ! can signify forcing a change (side effects). To avoid ambiguity, the correct syntax is f() !='x'.

Because ThingsDB is backwards compatible, it still parses the existing code correctly, and you can safely ignore this warning.

How to resolve the warning:

1. Re-apply the procedure or method: Re-saving the affected code forces ThingsDB to rewrite and format it according to the updated syntax rules.
2. Wait for the change log to rotate: The warning may still appear briefly after re-applying. ThingsDB maintains an internal change log, so the warning will fully disappear once the log entry containing the old code format is no longer loaded on startup.
